Opening window with multiple keypress?? Newbie

Robin Goodfellow · Jun 30, 2003

Hi,

I know that this is probably very basic but I am looking for a bit of help.
I have a website running at the moment but I want to have a log in screen
that is hidden, so I want to be able to capture a specific sequence of
kepress' or even multiple keys held down at the same time to open the login
screen.

I have been trying to read up on this but I am getting nowhere at all, could
anyone please help.

Thanks in advance

To get you started:

<script>
function fill(x){
if(x==27){empty();return}
if(x!=13)return // any other key will just append a char.
if(document.getElementById("in").value.toLowerCase()=="mypassword")
location.href="/loggedin.html"
// else:
empty()
}

function empty(){
document.getElementById("in").value=""
document.getElementById("in").focus()
}
</script>

<body
onload='empty()'
oncontextmenu="empty();return false">

<input id=in name=in value=""
style="visibility:hidden;"
onkeydown="fill(event.keyCode)">

Securitywise clientside passwords are nonsense, of course !!

Try something like this:
---
function doSomething() {alert("SUCCESS!");}

document.documentElement.onkeypress = function (event) {
event = event || window.event; // IE sucks
var key = event.which || event.keyCode; // IE uses .keyCode, Moz uses .which
if ((key == 76 || key == 12 || key == 108) && // "L" "^L" or "l"
event.shiftKey && event.ctrlKey) {
doSomething();
if (event.preventDefault) { event.preventDefault(); }
else {event.returnValue = false;} // IE sucks
}
}
---
This triggers the doSomething function when you press Shift+Ctrl+L,
and works in Mozilla, IE6 and Opera in standards mode.
(I'm not sure whether the key==108 is necessary, but I would keep it
to be sure).

So would I put
<SCRIPT LANGUAGE="JavaScript1.2">
then your code
</SCRIPT>

do I need to put anything in the body, when I say begineer I mean I have
only been at this a couple of hours !!!
